摘要:

 [摘要] 目的:建立高效液相色谱(HPLC)监测环孢素A(CsA)血药浓度的方法,研究HPLC法和荧光偏振免疫法(TDx)法测定人全血中CsA浓度的相关性;方法:分别用TDx法和HPLC法测定92例肾移植患者的CsA血药浓度,测定值用t检验和线性回归方法进行分析;结果:TDX法和HPLC法测定全血中CsA浓度具有相关性,线性回归方程为:Y=0.826X+8.318 (r = 0.967,n=92,P<0.01),TDX测定值比HPLC测定值平均高25.44%;结论:TDX测定值明显高于HPLC测定值,两种测定方法所得结果存在显著性差异。

Abstract:

ABSTRACT Objective:To evaluate the correlation between the whole blood cyclosporine A (CsA) concentrations by HPLC and TDx.Methodology: A total of ninety two samples from renal allograft recipients were determined by HPLC and TDx assay.Regression analyses were performed (HPLC results as dependant.TDx as independant variable) for the evaluation of correlation.Results : TDx results were higher (25.4%) than those from HPLC.There existed good correlation with least-squares equation Y=0.826X+8.318 (n=92,r=0.967).Conclusion: There were significant differences in determination result of CsA between HPLC system and TDx。
